Need calculations for wall climbing RC car

Click For Summary
SUMMARY

This discussion focuses on the calculations necessary for designing a wall-climbing remote-controlled (RC) car, specifically imitating the Airhog zero gravity climber. Key considerations include deriving equations for suction pressure and selecting appropriate motors for suction fans. The design utilizes an air venturi system, necessitating calculations for the volume of suction cups, airflow requirements, pressure, area for force calculations, and the coefficient of static friction to prevent sliding down walls.

PREREQUISITES
  • Understanding of fluid dynamics principles, particularly air venturi systems.
  • Knowledge of suction pressure calculations and their application in RC vehicles.
  • Familiarity with motor selection criteria for driving suction fans.
  • Basic physics concepts related to pressure, area, and force calculations.
NEXT STEPS
  • Research suction pressure calculations specific to air venturi systems.
  • Learn about motor specifications and selection for suction applications.
  • Study the relationship between suction cup volume and airflow requirements.
  • Explore the coefficient of static friction and its impact on wall-climbing designs.
USEFUL FOR

RC car enthusiasts, mechanical engineers, hobbyists designing wall-climbing vehicles, and anyone interested in the application of suction technology in robotics.

I am trying to imitate the Airhog zero gravity climber

one of these
http://www.gmhummer.com/forums/showthread.php?t=111

can someone please help me regarding derieving equations for the suction pressure required and regarding selection of motors for driving suction fans.
the toy basically uses an air venturi system so i am a bit unsure that the equations of a hovercraft would be applicable.
please help me out.

can someone answer my query
 
Hmm.. I think that the volume of the suction cups will need to be calculated into the airflow requirement of the venturi. Other than that, you have pressure and area to find force and you'll need a coefficient of static friction to know if it'll slide down the wall.
